Light Intensity Luminous intensity is measured and reported in foot-candles (ft-c) or in lux (lx). Light meters are commonly referred to as lux meters. One lux is equal to one lumen per square meter and one foot-candle is equal to one lumen per square foot. To convert measurements use the following formulae: foot-candle = lux x lux = foot-candle x HANNA s light measuring sensor is a photo diode that converts incident light into an electronic signal that is read and displayed on the meters LCD as Klx which is 1,000 lx. So multiply the reading by 92.9 to get the measurement in foot candles. Common examples of light Intensities Full Moon.001 Klx 1 lx.0929 ft-c Street Lighting.01 Klx 10 lx.929 ft-c Workspace Lighting.1-1 Klx 100-1,000 lx ft-c Surgery Lighting 10 Klx 10,000 lx 929 ft-c Sunshine 100 Klx 100,000 lx 9,290 ft-c HI is supplied with (1) 9V battery and instruction manual. Lux Three measurement ranges Light sensor attached to 1.5 meter coaxial cable Rugged, waterproof case Plant Light Requirements Light provides the energy source needed for plants to manufacture food (photosynthesis). The amount of light is commonly measured in foot-candles (ft-c) or lux. Plants differ greatly in their light intensity requirements. Indoor plants are often classi ed by the amount of light necessary for growth: Low (minimum 1.1 Klx,.8 to 2.1 preferred for good growth) Medium (minimum 1.1 to 1.6 Klx, 2.1 to 5.4 preferred) High (minimum 1.6 to 10.8 Klx, 5.4 to 10.8 preferred) Very high (minimum 10.8 Klx, preferred) About 1.1 Klx for 12 hours per day are necessary simply to maintain plant quality for one year and at least 2.1 Klx for 12 hours per day are necessary for foliage plants to manifest any bene t from fertilization. While lack of suf cient light results in poor plant growth, too much light can also be harmful. Shade plants cannot tolerate excessively high light levels. When a plant receives too much direct light, the leaves bleach or scald, sometimes dying. This often happens after moving a plant outdoors in direct light. Any changes in light intensity should be gradual. 11

12 N/P/K HI 83215/HI Grow Master for Nutrient Analysis Kit Nitrogen, Phosphorus, Potassium and Ammonia Meter HI & HI are designed for the hydroponics industry to measure 7 nutrients commonly present in fertilizer enriched solutions. Ammonia, phosphorus, nitrate and potassium can be measured in three distinct ranges of low, medium and high concentrations. This way accuracy is maximized for each nutrient and for every concentration. Due to simplicity of operation, you no longer need to send off your samples and wait for the results to come back. With the HI and HI 83225, you can test the presence and strength of nutrients right on the spot. This can translate itself into a substantial saving and improved yield over a period of time. Plant Nutrition The three elements that are most needed by plants are nitrogen (N), phosphorous (P) and potassium (K). This is the reason why they are called macronutrients and should be given to plants. Accurate Easy to use Economical Tests Nitrogen is indispensable for the plant s life and is a key factor in fertilization. Nitrogen allows the development of the vegetative activity of the plant, in particular, causes lengthening of trunks and sprouts and increases the production of foliage and fruits. An excess of nitrogen weakens the plants structure creating an unbalanced relationship between the leaves and the stalks. In addition, the plant becomes less resistant to diseases. Phosphorous is an important element in the composition of DNA and RNA, the regulators of the energetic exchange (ATP & ADP), as well as the reserve substances in seeds and bulbs. It contributes to the formation of buds, roots, blooming, and ligni cation. A lack of phosphorous results in: sti ing of plant, slow growth, a reduction of production, smaller fruits and a lower expansion of the roots. Even if Potassium is not a constituent of important compounds, it plays a remarkable role in many physiological activities like the control of cellular turgor and the accumulation of carbohydrates. It increases the size of fruits, their avor, as well 12 as yielding a positive effect on the color and fragrance of owers. Potassium also makes plants more resistant to disease. 12 Don t Wait for lab Results!

13 Refractometer Digital Brix Refractometer Take Your Measurements to the Next Level HANNA Digital Refractometers are rugged portable, water resistant devices that bene t from HANNA s years of experience as a manufacturer of analytical instruments. The measurement of refractive index is simple and quick. Samples are measured after a simple user calibration with deionized or distilled water. Within seconds the instrument measures the refractive index of the sample and converts it to % Brix concentration units. (in C or F) is displayed simultaneously with measurement on the large, dual level display along with other helpful message codes. Battery life on display A crop with a higher Brix level results in a better tasting, more notorious yield. You can test the Brix of leaves to check nutrients balance before harvest. If the Brix is low, the nutrients are not being dosed in suf cient quantity and/or correct proportion.

15 Control System MINI FERTIGATION SYSTEM The HI 5000 is an all-in-one, ready to use control system. Compact and versatile, the Mini Fertigator brings precision nutrient and acid control to professional growers and advanced home growers alike. The Mini Fertigator is easy to install and comes completely pre-assembled. To install the unit, simply attach two pipes and plug into the power cord. No wiring and no assembly required! To inject nutrients, the Mini Fertigator uses a venturi so there are no high-maintenance peristaltic pumps to worry about. HANNA s included Blackstone pump can handle full-strength acid, so there is no need to risk an accident with dilution. HANNA s at-tipped probes are also highly resistant to fouling and clogging.
